Thank you, upgrade was successful!

I'm running a full node (v0.15.1) on my Raspberry Pi 3 with Rasbian and I want to upgrade my node to 0.16.0. The bitcoin.org description on how to upgrade Bitcoin Core was not rly helpfull ("just copy over bitcoind" - very user friendly ^^).
Anyway, I looked for an answer on Google and also in this forum but nothing rly helped me.

For the first installation i used the following lines (from this description: https://github.com/MrChrisJ/fullnode/blob/master/Setup_Guides/Setup_Jessie_Bitcoin_Core_0.13.2.md):

cd ~/bin
git clone -b v0.15.1 https://github.com/bitcoin/bitcoin
cd bitcoin/
./autogen.sh
./configure CPPFLAGS="-I/usr/local/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/usr/local/BerkeleyDB.4.8/lib" --enable-upnp-default --with-gui=qt4
make -j2
sudo make install

First I thought about to just run the same code again (with v0.16.0 instead of v0.15.1) but at bitcoin.org they wrote that I have to "just copy over bitcoind" so idk want is meant by that.

So if someone can send me a (noob-userfriendly) solution I would rly appreciate that.
